Error  The 'inject' directive expects an identifier. 

Answer: When developing in Asp.Net Core 3.1 and you try to inject a Service in the View, all of a sudden you see the Error  "The 'inject' directive expects an identifier". Below is the solution:

• Look into your View specifically on the "@inject" directive, you will notice that one of the @inject Service does not have an instance name. 
  - @inject expects you to state a type of the object you are injecting into the View then define an instance. Look at it like instantiating a new object but in this case, you're only creating an instance that you will later use to access the functions defined in the Mock Repository or an Interface.
  
  

  @inject UserManager<YourService> //This is the wrong way to inject a dependency
  @inject IViewLocalizer localizer //This is the correct way to inject a dependency?
